I knew the Hemi was great but..........

Those engines were not even close to factory specs-its was a joke,not even car crafts build up a few years ago with edelbrock heads and comp cams was a good comparison to factory performance.To really see what they were were from the factory would be painstakingly boring due to the lack of aftermarket parts getting to be used so no one (car mags/shows) really wants to do a apples to apples comparison-a whole lotta money and time spent with no real payoff in their eyes.
